Reducing energy use, increasing the use of renewable energy sources, and adapting to stricter building regulations and certification systems – these are all examples of the challenges facing the building industry and society. Looking at the energy supply at a larger scale than a single building, like a neighborhood or a city, the stack effect of peak power demands can cause problems on the product

In scanning probe microscopy the properties of the tip is crucial in determining which information that can be obtained from the resulting images and spectroscopy. Ordinarily metal tips are used for scanning, however by using semiconducting nanowires as tips one would have very well defined probes with more advanced possibilities for spectroscopic measurements. However, currently creating such hig

Utveckling av algoritm som avgör filterstatusen hos dialysmaskiner Många människor världen över dör för att de inte har råd med dialysbehandling. För att minska kostnaderna har det i detta exjobb utvecklats en algoritm som kan användas i en framtida serviceindikator för filter i dialysmaskiner. Resultaten ser lovande ut. Kronisk njursjukdom beskriver ett tillstånd av progressivt förlorad njurfunDialysis is a life-sustaining treatment for many people around the world. In or- der to meet the high demands on the dialysis machines, replaceable parts must be exchanged in proper time. Condition based maintenance (CBM) bases its service decisions on the actual health status of the component. The goal of this master’s thesis was to develop an algorithm based on machine learning, constituting the

This paper studies whether Swedish workers use the unemployment insurance (UI) system as a pathway to retirement. We use longitudinal register data consisting of weekly UI benefit payments for the period 1999 to 2015. In Sweden, individuals are eligible for UI benefits for a maximum of 427 days. This creates an artificial benefit threshold at 427 days prior to the official retirement age. We use a

We live in a time where there is an increasing focus on the environment, in terms of classification of vehicle emission standards and environmental zones. Along with this and the fierce market competition that exists, it is odd that a greater effort has not been made in making material-transport more effective by renewing the tarmac on our road-network. The purpose of this report is to show the sa

Syftet med denna undersökning är att studera hur en uppköpares teknologiska karaktär påverkar onormal avkastning vid högteknologiska förvärv. Genom att gruppera de förvärvande bolagen efter industritillhörighet och grad av teknikintensitet strävar författarna att skapa en djupare förståelse kring vilken typ av bolag som kan förväntas generera störst värde åt sina aktieägare vid högteknologiska för

Dividend is a much-debated subject and has been compared to a puzzle with no sole solution to explain why firms pay dividend. Many academics have tried to determine what company variables determines a firm’s dividend policy. These studies have provided different explanatory variables to explain why firms pay dividends. Therefore, the main purpose of this study was to fill in a piece of the dividen

The impressive growth of smart city initiatives can be widely witnessed worldwide. These cities are launched at the effort to improve quality of citizens’ life and help city planners optimize and operationalize management of urban infrastructures. Smart cities are characterized by technologies and systems that are sources of high-volume and high-variety data sources which can be gathered, stored a

Tubular heating elements, produced by Backer AB are today commonly used, serving as systems for intelligent heating in automotive, medical and household industries. Tubular heating element consists of a mantle, resistance wire, electrical insulation (magnesium oxide) and a sealing. When active, an electric current transfers heat from the resistance wire of the heating element to the surroundings w

The genome of the Belinda variety of the hexaploid oat (Avena sativa) has recently been sequenced and assembled. This project aims to improve the assembly by clustering the thousands of scaffolds into their three ancestral subgenomes using Principle Component Analysis (PCA) of kmer and repeat-element frequencies. The method was developed using a chromosome level assembly of hexaploid Wheat (Tritiu
